摘要： PROBLEM TO BE SOLVED: To suppress an image density variation due to the deviation of recording positions between dots recorded by different passes and to reduce an image defect due to a stripe while reducing the load of data processing when a recording element group is recorded by M (M is integer of 3 or more) times of relative movement.SOLUTION: The number of multi-valued image data (24-1 to 2) fewer than that of a M pass is generated by input image data and a plurality of quantized data (26-1 to 2) is generated by quantizing the multi-valued image data, respectively. Then at least one piece of the quantized data is divided into the quantized data having a complementary relationship corresponding to a plurality of passes. At that time, the quantized data corresponding to the plurality of passes is generated so that a recording duty of an edge portion of the recording element group is set lower than a recording duty of a central portion of the recording element group.

摘要： PROBLEM TO BE SOLVED: To measure the color of a measuring image in stable state while minimizing the waiting time from when the measuring image used for calibration of recording characteristics is dried till when measurement is started in an inkjet recorder.SOLUTION: Based on the information of ink types and the information of the quantity of ink to be placed, a waiting time Ts is determined with reference to a waiting time reference table A (step 6). In addition, a dried recording sheet is conveyed to a waiting area 9 and stopped (step 7), the time T after stoppage is clocked, and measurement processing of next process is waited until the time T reaches the waiting time Ts. When the waiting time Ts is reached, density of a patch recorded on the recording sheet is measured using a measuring instrument 10 (steps 8 and 9). Consequently, a recording head can be calibrated in a state with no excess or shortage in the waiting time after drying before measurement. The color of a measuring image can thereby be measured in a stable state while minimizing the waiting time.

摘要： PROBLEM TO BE SOLVED: To also suppress granularity deterioration caused by overlapping of dots while suppressing image density variations caused by a conveyance error or the like of a recording medium when recording an image according to a multi-path system.
SOLUTION: Multi-valued image data 501 corresponding to a pixel area are divided into first scanning multi-valued data 502, first and second scanning common multi-valued data 503, and second scanning multi-valued data 504. Quantization processing is executed on each of the multi-valued data 502 to 504 to generate first scanning quantized data 505, first and second scanning common quantized data 506, and second scanning quantized data 507. After that, these pieces of quantized data 505 to 507 are combined for each scanning to generate first scanning combined quantized data 508 and second scanning combined quantized data 509. Accordingly, the amount of pixels (the amount of overlapping dots) where dots are recorded every time when scanning of two or more times are carried out is controlled, and while suppressing the image density variations, granularity is held to a low level.

摘要： PROBLEM TO BE SOLVED: To suppress density fluctuation by recording position deviation of dots to be recorded by different paths even while reducing loads of data processing when recording is performed to a pixel area by M (M is the integer of ≥2) paths using N (N is the integer of ≥2) recording element groups.SOLUTION: First, pieces of multivalued image data (24-1 to 2) corresponding to the M paths are generated from input image data, and pieces of quantized data (26-1 to 2) corresponding to the M paths are generated by quantizing each of the multivalued image data corresponding to the M paths. After that, each of the pieces of quantized data corresponding to the M paths is divided into pieces of quantized data having complementary relation corresponding to the N recording element groups. Thus, pieces of quantized data (28-1 to 4) for the M paths by the N recording element groups are obtained. According to this configuration, the density fluctuation by the recording position deviation between the M paths is suppressed, and the loads of quantization processing are reduced since the number of pieces of data for quantization processing can be reduced.
摘要翻译：要解决的问题：为了通过记录由不同路径记录的点的位置偏移来抑制密度波动，即使当通过M（M是≥2的整数）进行记录时，数据处理的负荷减少为N （N是≥2的整数）记录元素组。解决方案：首先，从输入图像数据和多个量化数据（26-1）生成与M个路径相对应的多个图像数据（24-1至2）通过对与M路径对应的多值图像数据进行量化来生成与M个路径对应的图像数据。之后，对应于M个路径的每个量化数据被划分为与N个记录元件组对应的具有互补关系的量化数据。因此，获得由N个记录元件组的M个路径的量化数据（28-1至4）。根据该结构，能够抑制由M个路径之间的记录位置偏差引起的浓度波动，并且由于可以减少用于量化处理的数据数量，所以量化处理的负荷减小。

摘要： PROBLEM TO BE SOLVED: To provide a recording apparatus and a recording method which can output a uniform and smooth image in the whole area of the recording medium without permitting a recordable ratio of each recording scan to have a deviation, even if a sudden conveyance shift occurs. SOLUTION: When performing multipass recording of 2M passes, a mask wherein a recordable area overlapping ratio straddling between Pass M and Pass M+1 is set higher than the recordable area overlapping ratio straddling between other two consecutive passes is used. Thereby, even if a complementary relationship of dots collapses by a sudden conveyance shift etc. and a density reduction is anticipated, increase of the density is accelerated, by an overlapped dot being separated and it becomes possible to mitigate the density reduction.
